Carl (mc=35 kg) and diane (md=28 kg) are sitting on a wagon (mwagon = 22 kg) that starts at rest (carl and diane are fixed to the wagon, which pushes and pulls them along with the wagon). diane throws a ball (mball=1.5 kg) to carl. diane throws the ball so that it has a momentum of 34 kg m/s to the left, causing the wagon to move to the right at 0.4 m/s.

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
